WALL-COVERING AND P To all whom it may concern Be 1t known that 1, JOHN D. WIGGIN, of Montclair, in the county of Essex, and in the State of New Jersey, have invented a certain new and useful Improvement in Wall-Coverings and Processes of Making Same, and do hereby declare that the following 1s a full, clear, and exact description thereof.

fect due to weaving, which practically shall' not be marred in appearance by imperfect matching together of neighboring pieces of the goods, as when pasted upon a .wall, and to such ends my invention consists in a wall or other covering and process of making the same hereinafter specified.

In the accompanying drawing The figure shows a wall covering embodying my invention.

I shall describe that embodiment of my invention, which is the best embodiment known to me, but such description is to be taken as illustrative only of many embodiments of which my invention is capable. I use as a base for my'covering, a woven goods having uneven threads in which the pattern 1s not accurately duplicated. The class of goods used in the illustrated embodiment is what is known as slub yarn goods, or

- goods in which slubs are formed in the yarn; for instance, by more or less suspending the twisting .of the thread in the spinning operation, thus forming enlargements in the thread at intervals. When, for instance, such threads are used in the filling known process. The mercerizing causes the slubs. to be rounded up and hardened so that they are all brought out into relief.

This makes the weaving more visible and I emphasizes the contrast between the pattern 'formed bythe slubs and the body ofthe goods. L

The fabric isthen dyed (if the color de- ROGESS or MAKING SAME.

sired is sufiiciently dark to permit dyeing),

the fabric being dipped in the dye, and both sides receiving the color. This is done on a padder with dye liquor preferably composed of an aqueous solution of dye stuff, and a stiffener, which latter may be glue, casein, dextrin, starch, flour, soluble gums, (as tragacanth or arabic), or other stiffening material, or a combination of the foregoing. Next the fabric is dried, preferably over heated cylinders, the g'OOdS being preferably stretched laterally during this operation. A coating is put on the back of the fabric by a coating machine, the purpose of which coating is to enable the fabric to retain its KI shape after it is pasted and cut and while it-is being hung, while also permitting-the paste to get sufiicient hold on the fabric to secure good adhesion. This back coating may be of any well-known composition, as

my invention does not relate specifically to it. The first coat of color is then put on the face of thefabric by a printing machine having an intaglio printing surface and known as a pin roller. The composition of this coating may, for example, be

as follows: 20 parts cooked until homogeneous; (6 parts cornstarch; 48 parts water;) 12 parts solution, (1 part gum tragacanth, 16 parts water). 4 partssolutlon, (2 parts fine mica, 3 parts water). Necessary coloring matter.

The mica in the foregoing run is, applied to help give light and brilliancy to the fab-- ric. The above ingredients and proportions may be considerably varied from this formula, although I prefer them as stated.

The fabric is then calendered, preferably by means of a friction calender.

The material may be left inthis condition,.or I may further emphasize the design,

such as that made by the slubs, as by'printing on the tops of the threads a water color in a suitable binder. The usual engravedprinting roll may be used forthis purpose. or in placeof such printing an excess of color may be applied to thefabric and then scraped from the tops of the threads only,

leaving the. bottoms of the threads a deeper or a different color. than the top.

in the making of the fabric, and that I further emphasize the elevations by swelling, as 'by mercerizing or hard sizing. I prefer the It'will be observed that I produce the I desired,'elevations by introducing elevations mercerizing as it gives a silky foundation for the coatings, so that the elevations shine more than they-otherwise would.

ll am aware that many changes may be made in the above described embodiment of my invention, and I desire not to be limited beyond the necessary intendrnent of my claims and the requirements of the prior art.

I claim:

1. A wall or other covering fabric having as a basis woven goods aving uneven threads, the'unevennesses of which have been enlarged after the Weaving of the fabric.

2, A. wall or other covering fabric having as a basis woven goods having uneven threads, threads of which have been made more prominent by impregnation.

8. A wall or other covering fabric having as a bass woven goods having uneven threads, threads of which have been emphasized by impregnation.

4e. A. wall orother covering fabric having as a basis woven goods having uneven threads, threads of which have been relativelyelevated by impregnation.

5. A wall or other covering fabric having as a basis woven goods having uneven threads, threads of which have been rounded up by impregnation. e

-. 6. A. wall or other covering fabric having as a basis woven goods having uneven threads, the larger portions of the threads of which have been made more prominent by treatment after weaving.

7. A wall or other covering fabric having as a basis woven goods having uneven threads, the optically more prominent por "tively elevated.

tions of the threads "of which have been emphasized by treatment after weaving.

8.;A wall or other covering fabric having as a basis woven goods having uneven threads, the optically more prominent portions of the threads'of which have been rela- 9. A wall or other covering fabric having.
